Method for interpreting data measured in a hydrocarbon well in production

A method for calculating the relative volumetric flow-rate of at least one of the phases of a multi-phase effluent flowing in a well, the method comprising a first step of acquiring local volumetric fractions and/or velocities of the phases across the section of the well at a certain depth. The meth...

Zusammenfassung:	A method for calculating the relative volumetric flow-rate of at least one of the phases of a multi-phase effluent flowing in a well, the method comprising a first step of acquiring local volumetric fractions and/or velocities of the phases across the section of the well at a certain depth. The method further comprises: corrections of the volumetric fraction and/or velocity measurements in order to make them consistent with each other; selection of a suitable flow model which mathematically represents the effluent flow; interpolation of the local volumetric fraction and/or velocity measurements by the flow model to obtain a volumetric fraction and/or velocity profile; and calculation of the relative volumetric flow-rates by integration of the volumetric fraction and/or velocity profiles over the section of the well at the certain depth.
